It's true that we look at full frame lenses and of course full frame cameras quite a bit. In fact, we do it a lot. But that's because most of the sexy-time lenses are the ones that cover the full 35mm frame. Although we're aware that the majority of DSLR users are using crop-sensored camras. So, we're going to take a look at "standard lenses" for crop sensored cameras.....starting with the Sigma 30mm f/1.4 (http://bit.ly/Sigma30mm-14) and Nikon 35mm f/1.8 DX(http://bit.ly/AF-S35mm) .
